Two experiments were conducted to evaluate effects of corn distillers dried grains with solubles (DDGS) on growth performance and health status of weanling pigs. The first experiment evaluated effects of increasing concentrations of DDGS on growth performance and health of weanling pigs. For Exp. 1, dietary treatments included: 1) control (CTL); 2) 0% DDGS (0% DDGS in Phase 2, and 30% DDGS in Phase 3); 3) 5% DDGS (5% DDGS in Phase 2, and 30% DDGS in Phase 3); and 4) 30% DDGS (Phases 2 and 3). Overall, pigs fed 30% DDGS during Phases 2 and 3 had decreased (22.1 vs. 25.1 and 24.0 kg; P = 0.003) BW compared to CTL pigs and pigs that only received DDGS during Phase 3. In addition, pigs fed 5 or 30% DDGS in Phase 2 had decreased (422.7 or 390.0 vs. 468.2 g; P = 0.003) ADG compared to CTL pigs. However, pigs fed 0% DDGS during Phase 2 had similar BW, ADG, and ADFI compared to CTL pigs. Experiment 2 was conducted to evaluate effects of DDGS, lactose, and their interaction on growth performance and health of weanling pigs. Dietary treatments included: 1) CTL; 2) lactose (20%); 3) DDGS (15%); and 4) lactose + DDGS. Diets of interest were fed during Phase 1 (d 0 to14) and a common diet was fed during Phase 2 (d 14 to 28). Pigs receiving DDGS in Phase 1 had greater ADG (576.2 vs. 534.6 g; P = 0.01) and ADFI (814.9 vs. 751.6 g; P = 0.01) during Phase 2 compared to non-DDGS fed pigs. Pigs receiving lactose during Phase 1 had greater ADG (214.7 vs. 177.2 g; P = 0.01), G:F (741.0 vs. 660.3 g/kg; P = 0.01), and tended to have greater ADFI (289.3 vs. 267.6 g; P = 0.07) during Phase 1 but decreased (537.7 vs. 573.1 g; P = 0.09) ADG during Phase 2. Serum Ig analyses and fecal microbial profiling were conducted in both experiments as indicators of health status. No effects of dietary treatment were observed for serum Ig in either experiment. Fecal microbial profiling resulted in statistically significant effects of dietary treatment with respect to microbial similarity and diversity indices (Exp. 1), and lactic acid producing bacteria (Exp. 2) where main effects of both lactose and DDGS were observed with respect to putative L. reuteri (P < 0.05). Results from Exp. 1 indicate that low concentrations of DDGS early in the nursery phase may negatively affect growth performance; however, growth performance may be maintained when inclusion of high concentrations (30%) of DDGS is delayed until the late nursery period. Results from Exp. 2 indicate that lactose may be incorporated in nursery diets containing DDGS to help maintain growth performance, and DDGS and lactose may affect fecal microbial profiles. |
